in order to innige dem' the construction, the sppiiootion, ond. the operation of our invention We will now take up s description thereof, in which We 'vviii set forth the eolistnetion enti operation as fuiiy and es eonipiehensiveiy es We may.

iin most instances the trensmission is ioesteoi iieiovv the Hooi* ot the :iront portion of en eotomo'biie. The soiiizsee of the ioor heingl denoted in L'Fig. i by the iine rihe transmission esse is denoted 'foy the letter B. Mounted on. anzi forming the eovei oi' the transmission esse is the oontioi-iooiz, whieh eonipiises e hoiiovv Toe-se from around the lowes edge of which `entendis the flange il thi'onggh 'which the hoits E sie inseiteoi to seeoie the eontioifiioiit in position on the transmis ion essie Extending upward i'i'on the hose C is 'the main housing F through which the eoitroi lever Gr operates, and in the upper portion of Whioh it is pivoted foi* universal .movements in the usual "mennen The iower end of the lever G is adopted to move the shifting-rods H and ii enciwise.' The seid rods are siidabiy mounted, psleilei with each other, in open tures therefor formed through the oase C.

Esch et the ioiiis J and K is secured to one oi the rods H' und i, and they :we so mounted es to @suse them to shift the gears located in the' esse ii when the iever G is opeioted in thensus] meneer. l

Ali of seid ports :we of on ordinary construction and no eieim is inode thereto, neither is oni' invention to be liiniteci to the me se construction mentioned.

The invention proper comprises e second ary housing, or projection i., which extends ont centrally from one end of 'the housings, iF, with which n stood that the housing; 1, the housing; it, the base U, and the :Piange D shouid he one integgiai casting.

Numeri-ils 3 and l designate balls, the same being located in the. aperture 2, and they are disposed between the rods and 1. The size ot said balls are such as to loosely tit in the aperture 2, and their combined diameters are only slightly less than is the distance between the rodsyll'il and I,

l `ormed in the" opposing sides ofthe rods H and 1 are theiespective segmental notches 5 and whose"curwiture corresponds with the curvature ot the balls 3 and l which may tit therein as slio'wn. -The location of said notches 5 and t5' are such. that when the rods H and l. are moved to shift the gears into neutral position the Said notches will be directly opposite and in alinement with the balls 3 angle, in which position they are indicated in 2 and llxtending downward from the center of the housing '1 is the comparatively large aperture 7, which is round in cross'section; and concentric vtherewith and continuing downward through tho housing' 1 is the smaller aperture 8, the same being of less diameter than the aperture 7, and it intersects the aperture at. a point midway oi the rods il and '1. By reason ot the dilerence in the diameter ot' the apertures 7 and a' there a shoulder 9` formed at the base ot' the aperture 7.

Numeral 10 denotes the barrel of the lock proper, the 'same being ot' ordinary arrangement imi'natcrial to this invention, except that it las a tumbler 11 operative therein which is adapted to be rotated by the key L which is adapted to be inserted in the keyhole l2, whereby the plunger 13, which eX tends through one side ot the. barrel, may be drawn in flush with the periphery of the barrel when said key is turned to a certain position. The barrel 10 is adapted to be inserted snugly into the aperture 7, with its upper end tlusli with the top ot' the housing 1, and with its` lower end some distance above the shoulder 9. A. slot 14 is formed` iu the housing l and it opens into the apern ture i', and the plunger 13 is adapted to enter thereinto as shown in Fig.y l. The Said slot. or :avit-y, Il may be formed before the barrel l() -is placed in position by inserting` a' tool through the aperture 15 which is formed opposite thereto in the Wall of the housing' 1r` as shown in Fig. 1.

Formed in the side ot' the barrel 10 isa slot, or cavityvv 1o. A screw 17 is threaded through the wall of the housinff 1 with the point of the screw located in the slot 16, thereby allowing the barrel to bc moved up and down within the limits ot the slot 16.

A holt.. or stom, 18 extends down from the 'center ot the barrel 1() and it slifdably lits and et, as shown in Fig. 52. Surrounding thel bolt 18 is the helical spring 20, whose upper end contacts with the under 'face of the barrel 10 and its lower end contacts with the shoulder t), and its tensionis such 'as to normally press the barrel upward to its limit ot movement.

The construction above described relates to locking the machine in neutral condition, however it may be locked in gear in reverse condition by simply providing` the notch 21 in the rod 1, which notch corresponds with the notch G, then it' the lever G be moved to reverse position the rod I will be moved to such position as will bring vthe notch 21 in alinement with the aperture 2, theriby inoviding means for the machine to be locked in such condition that it could be' operated in reverse dectiorn'that is backward.

In practice it will be apparent that il the plunger 13 be drawn in, that is tiush with the barrel 10, by turning the tumbler l1 by moans of the key L, that the spring 20 will then press the barrel 10 upi i: rd to the limit permitted by the slot lo, thereby removing the bolt 1S from between. the balls 3 and Ll, thereby allowing the balls to assume the positions in which the)y are shown in Fig. 3, and thereby permitting the shitting rods H and I to slide forward and backward in the usual manner for shitting the gears to various speeds.

Desiring now to loclt` the machine one has only to move the shift-imaV lever G to neutral position, thereby bringing the rods H and I to the posit-ions in which they are shown in Fig. 3. Then by pressing down on the barrel 10 it evident that the bolt 18 will be driven in between the balls 3 and 4, forcing them apart, and pressingthem into the notches 5 and G, as shown in Fig. 2. lVhen the upper surface of the barrel 10 becomes liush with 'the upper surface ot' the housin l the plunger 123 will enter the .slot 14, at. the same time the lower end of the bolt 18 will be located between 'said balls, and therefore the shitting means will be absolutely secured and locked.

From the above it is evident that the rods H and l can not be moved as long as the bolt 18 remains down, as in Fig. 2, and it would therefore be impossible for one. to place the machine in rear whereby it could be driven until the bolt 18 is moved upward, and evidently this could not be done until the tumbler l1 was turned to remove theplunger 13 from the aperture or slot 14, and the barrel be raised upward to its limit. of movement.

lt is evident. that one does not haveto use the kevin locking the device, there beine: only two movements required: placingr the shitting; lever in neutral or reverse position, and pressing down on the barrel until removing the bolt from .between lill A not be operated unless 'case ot .incassa the plunger 13 enters the cavity ld. lend `then to release the device one has only to insert the key L in the keyhole-l2, and then by giving a slight Itwist to the hey the plunger will bevvdrawn in 20 will press the barrel l0 upward, thereby -the balls, and theretcre permitting the shifting rods to be movil in the usual manner.

lt Should be noticed that it would be abn solutely impossible to break or to remove the locking means, and that the machine could one be provided with a particular key to lit thatparticular tumhier, thereby accomplising the objects of this invention.

By reason of the arrangement and the location of the parts as herein set forth it will be seen that all of the part ot our invention are inclosedY within the metal of the transmission, and that access thereto cannot be had until the lock is in unlocked condition.

Having now fully shown and described cui1 invention, what ive/claim and desire to secure by Letters `Patent of the United States, is

l. In conibination with the transmission of an automobile having a case and a pair of shifting rods operative parallel with each other through the ease, a locking mechanism formed integral with and inclosed by the case and comprising a ball for each shitting rod, said balls beinp,- normali)7 out of 'thc path of the respective shitting rods, a plunger bolt adapted to be inserted between said balls to force them apart and into notches therefor formed in the shifting rods whereby a portion ofeach ball will be in the path ot' its respective shitting rod, and means for locking the plunger bolt in position between said balls, substantially as set forth.

2.
